The open-drain RESET output can be used to interface
to a µP with other logic levels. The open-drain output is
connected to a voltage from 0V to 5.5V as shown in
Figure 5. Generally, the pullup resistor connected to
RESET connects to the supply voltage that is being
monitored at the device’s V
systems use the open-drain output to level-shift from
the supervisor’s monitored supply to another supply
voltage. As the supervisor’s V
the device’s ability to sink current at RESET.

ity of RESET decreases drastically. The high-imped-
ance CMOS logic inputs connected to RESET can drift
to undetermined voltages. This presents no problems in
most applications, since most µPs and other circuitry
do not operate with V
tions where RESET must be valid down to 0, add a pull-
down resistor between the MAX16056/MAX16057
push-pull RESET output and GND. The resistor sinks
any stray leakage currents, holding RESET low (Figure
6). Choose a pulldown resistor that accommodates
leakages, such that RESET is not significantly loaded
and is capable of pulling to GND. The external pull-
down cannot be used with the open-drain RESET out-
put of the MAX16058/MAX16059.
